Introduction
After you have installed hardware components, you must first configure LSI 2308
SAS settings before you install an operating system and other software drivers.
Note: If you do not wish to configure LSI Software RAID settings, proceed
with the OS installation. For OS installation instructions, refer to related
documents posted on our website at www. supermicro.com.
1-1 Overview of the LSI 2308 SAS Controller
The LSI 2308 SAS Controller, which is based on the Fusion-MPT (Message Passing
Technology) architecture, integrates advanced SAS and PCI-Express technologies
to deliver a processor-based, cost-effective RAID management tool for mid-level
servers that require high system availability and redundancy without full-featured
RAID implementation. The supported Integrated RAID options include RAID 1 (Integrated Mirroring), RAID 1E (Integrated Mirroring Enhanced), RAID 0 (Integrated
Sriping) and RAID 10 (Integrated Mirroring and Striping). These RAID configurations
are easy to configure and should satisfy most internal RAID requirements.
The LSI 2308 Controller supports eight PCI-E lanes with transfer rates of up to 8.0
GT/s per lane for PCI-E 3.0, while remaining backwards compatible to the 5.0/2.5
GT/s data rate supported by PCI-E 2.0/1x. It also supports End-to-End CRC (ECRC)
with Advanced Error Reporting (AER), power management, hot plug support, and
legacy interrupt.
Features of the LSI 2308 Controller
The LSI SAS 2008 Controller supports the following features:
Integrated RAID
•RAID 0, RAID 1, RAID IE, and RAID 10 supported
PCI-Express to 8-Port SAS/SATA Controller with data rates of:

1-2 RAID Modes Supported by the LSI 2308 SAS
Controller
The LSI SAS/SATA 2308 Controller supports IR (Integrated RAID) Mode and IT
(Initiator and Target) Mode.
Note: These two RAID modes require different firmware and drivers. Be
sure to download the correct RAID mode driver before installing it to the
OS. For firmware downloads and assistance, please contact Supermicro
Technical Support at www.supermicro.com or Support@supermicro.com.
IR Mode Configuration
To create an IR RAID storage configuration, you will need to configure physical disk
drives into arrays first. An array is a group of one to eight physical disks treated by
a host computer as one large disk drive (logical drive). Only one RAID level can
be assigned to an array.
IT Mode (Initiator and Target Mode)
This is a Non-RAID mode. To use this mode, be sure to flash an IT mode firmware
to the EEPROM and install an IT Mode driver to the system OS.

LSI 2308 SAS Configuration Utility User's Manual
1-3 RAID Levels Supported by the LSI 2308 Controller
The LSI embedded Software Configuration utility adds RAID functionality to enhance
system efficiency and data security by supporting RAID 0, RAID 1, RAID 1E, and
RAID 10.
RAID 0 (Integrated Striping) can greatly enhance hard disk I/O performance by
striping data across multiple drives. RAID 1 (Integrated Mirroring) and RAID 1E
(Integrated Mirroring Enhanced) allow data to be simultaneously written to multiple
drives, increasing data integrity. RAID 10, combining RAID 1 and RAID 0, provides
superb system performance and system security.
Note: A maximum of 2 RAID volumes and 16 physical disk drives (includes
2 hot spares) is supported for onboard RAID in IR mode.
RAID 0
RAID 0 (Integrated Striping) can greatly enhance hard disk I/O performance by striping data across all disk drives in an array or drive group. This RAID configuration
does not provide data redundancy, but it offers the best RAID performance and a
high bandwidth. The following illustration provides a visual example of a RAID 0
drive group.

Chapter 1: Introduction to the LSI 2308 SAS Configuration Utility
RAID 1
RAID 1 (Integrated Mirroring) allows data to be simultaneously written to multiple
drives. This RAID configuration increases data integrity by providing redundancy,
but requires twice the amount of data storage capacity. Two drives are required to
complete a RAID 1 configuration. The following illustration provides a visual example
of a RAID 1 drive group.

RAID 1 Example
RAID 1E
RAID 1E (Integrated Mirroring Enhanced) is a non-standard RAID configuration
that combines data striping (RAID 0 functionality) with data redundancy (RAID 1
functionality). In this configuration, data is triped across all drives and a copy of
each stripe is stored on a different drive. RAID 1E requires at least 3 drives, with
additional drives added in pairs (total number of drives is an odd number). The
following illustration provides a visual example of a RAID 10 virtual drive group.

RAID 10
RAID 10 (a combination of RAID 1 and RAID 0) provides superb system performance and system security. RAID 10 stripes data across the primary disks in a
drive group and then duplicates that data to the secondary disks in a drive group.
RAID 10 requires a minimum of 4 drives. Any additional drives must be added in
pairs (6 drives, 8 drives, etc). The following illustration provides a visual example
of a RAID 10 virtual drive group.

Configuring the LSI 2308 IR Mode Settings
This chapter provides configuration instructions for the LSI 2308 SAS configuration utility for IR Mode settings. If you do not wish to configure LSI Software RAID
settings, skip this section and go directly to OS Installation. For OS installation
instructions, please refer to our website at www.supermicro.com.
Notes:
1. A maximum of 2 RAID volumes and 16 physical disk drives (includes 2
hot spares) is supported for onboard RAID in IR mode.
2. For system stability, do not use both SAS and SATA drives in the same
array.
2-1 Using the LSI 2308 Configuration Utility in IR Mode
Follow the steps indicated below to configure arrays and logical drives in SAS IR
Mode.
1. Power on the system.
2. When the LSI MPTSAS Initialization screen displays, press <CTRL> and <C>
to enter the LSI configuration utility (shown below).
LSI Configuration Utility

3. Highlight the LSI 2308 setting you would like to configure and press <Enter>
to display the configuration utility main page as shown below.
LSI Configuration Utility Main Page
4. Highlight Boot Support (see above) and press <-> or <+> to change the setting. Press <Enter> to select the desired setting. (The default setting for Boot
Support is Enabled BIOS & OS.)
Note: For more information on an item, press <F1> or <Shift F1> to access help information.

2-2 Creating RAID Volumes
In IR mode, you can create RAID 1, RAID 0, and RAID 1E/10 volumes. The procedure for creating each RAID volume is the same; however the amount of physical
disks in a volume varies for each configuration as follows:
•RAID 1: This configuration consists of 2 disk drives, including up to 2 optional
hot spares.
•RAID 0: This configuration consists of 2 to 10 disk drives.
•RAID 1E/10: This configuration consists of 3 to 10 disk drives, including up to
2 optional hot spares.
Use the following procedure to create a RAID 1, RAID 0, and RAID 1E/10 volumes
1. From the LSI Configuration Utility main page, select RAID Properties and
press <Enter> to display the RAID configuration options, as shown below.
RAID Configuration Options
2. Select the desired configuration option and press <Enter>. The following
screen displays.
Figure 2.3

LSI 2308 SAS Configuration Utility User's Manual
3. Use the arrow keys to navigate the following fields:
•Slot Num: This field indicates the slot numbers of the disk drives that will
be configured into the RAID volume.
•Device Identifier: This field indicates the manufacturer of the hard disk
drive.
•RAID Disk: This field indicates if the disk drive specified is a RAID device.
To change a non-RAID drive to a RAID drive, navigate to the RAID Disk
field for the desired drive and press <-> or <+> to select the drive for a
RAID volume. Press <C> to create a RAID volume. You can follow the same
procedure to change a RAID drive to a non-RAID drive.
Warning: When creating a RAID volume, all existing data on the disks will be erased.
•Drive Status: This field displays the status of the disk drive.
•Pred Fail (Predicting Failure): This field indicates if SMART (Self-Monitoring,
Analysis, and Reporting Technology) predicts that the disk drive will fail.
SMART is a monitoring system used to detect and report on the various
health conditions of a hard drive. If a hard disk failure is anticipated by
SMART, it is strongly recommended that you replace the hard drive before
creating a RAID volume on the disk drive.
•Size: This item displays the size (in GB) of the individual hard drive.
Notes:
1. The size of the volume created in a disk drive does not reflect the actual
size of the disk.
2. If a RAID set consists of two or more disk drives, the size of the RAID
volume indicates the total RAID volume created by all the disks within the
RAID set combined.
